Warehouse Roofing Repairs & Replacement

Box gutters: the warehouse weak point

The single biggest cause of warehouse leaks is the box gutter overflowing internally. These wide internal gutters silt up with leaves, dust and debris, the sumps and downpipes can't cope, and in a heavy Sydney downpour the water backs up over the gutter edge and straight into the building -- often metres away from where you'd expect. Undersized or blocked overflow provisions make it worse.

We clear and inspect box gutters, check the fall and sump capacity, and where the gutter is genuinely undersized we can widen it or add overflow outlets so the next storm goes down the pipe instead of onto your racking.

Protecting stock during the works

We plan warehouse jobs around your layout. That means identifying which bays sit under the work area, staging so we don't open the roof above high-value or moisture-sensitive stock, and keeping forklift and pedestrian routes clear. Where we must work over active racking, we lay protection and control debris so nothing lands on your product below.

We never strip more roof than we can make watertight the same day -- critical when there's a warehouse full of cardboard boxes underneath.

Skylights, ventilation and large-span sheeting

Warehouses rely on roof skylights for daytime light and on ridge vents or whirlybirds for heat control. Brittle old skylights are both a leak source and a serious fall hazard for anyone doing rooftop maintenance. We replace them with polycarbonate and add safety mesh. On the sheeting itself we re-fix perished fasteners, re-seal laps, and re-sheet sections that have corroded through.
